NONLINEAR DOUBLE-ARM OPTICAL TWEEZERS FOR 3D CONTROL MICROSPHERES

Nguyen Manh Thang

Abstract


In this paper, a new nonlinear double-arm optical tweezers combined Mach-Zenhder interferometer, objective lens and organic dye layer is proposed.  Based on the ray-optical and wave optical approximations, the expression describing the separation of two trap centers and laser intensity distribution are derived. The obtained results show that the separation between two trap centers, the laser intensity distribution, trap region’s area, optical trap efficiency can be controlled by tuning laser power. The proposed model is seen to be a double-arm optical tweezers for 3D control microsphere by optical method.
